Description
Chlamys opuntia is a species of marine bivalve mollusc, a scallop, belonging to the family Pectinidae. It is characterized by its distinctive fan-shaped shell, prominent radial ribs, and ear-like projections (auricles) near the hinge. This species is a filter feeder, playing an ecological role in marine environments by consuming phytoplankton and suspended organic matter.
